An example non-transitory computer-readable medium storing machine-readable instructions that, when executed by a processor, cause the processor to: set a graphical processing unit (GPU) power allocation, the GPU power allocation indicating power available for use by a GPU. The processor sets a processor power allocation, the processor power allocation indicating power available for use by the processor. The processor receives a GPU usage value and modifies the GPU power allocation to a modified GPU power allocation based on the GPU usage value. The processor modifies the processor power allocation to a modified processor power allocation based on the modification of the GPU power allocation.
